The Chelsea 871 Series Power Take-Off, part number 871XGFJW-D3RY or 871XGFJWD3RY, is a compact 10-bolt PowerShift (hydraulic) PTO designed for Allison transmission applications. The series delivers continuous torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous duty. Nine speed ratios and thirteen output options give installers broad flexibility across fire and rescue, refuse, truck crane, and pumper cleaner vocations. A ductile iron bearing cap, rated 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap work together to resist vibrational stress from modern engine designs. The Wet Spline pump flange protects both the PTO and pump shaft during continuous operation. The 871 Series also supports optional SmartStart for reduced shock load at start-up and Electronic Overspeed Control (EOC) to protect driven equipment. Call us to confirm proper fit for your specific installation.
